I just used pure omni light (max user), I think equivalent would be called "point light" in Maya.
It's the type of lights that cast rays everywhere, and you just need an "attenuation" settings to tell them where to (gradually) stop.

As for AO. You can do it in separate pass and compose it back in Photoshop.
It's really easy, just google some video tutorials.

I'll tweak with some point lights and see what kind of results I can get. I use quadratic lighting for fall off most of the time. As far as AO goes, I understand how to composite it, but have trouble configuring the actual node in Maya. On the other lights you mentioned for mood, do you have suggestions on how to set them up and what light types would be best?

Buy a copy of The Third Man: http://www.amazon.co.uk/The-Third-M...54109481&sr=8-1

Watch the end sequence (https://www.youtube.com/watch?v=qN84n-h4ObQ), find a shot or shots you like and copy it.

@ InfernalDarkness


can you show me how you set up your final gather settings for the scene you did? i've been messing with the settings on the light surface shader and my fg settings but can't get good results. I always get the FG splotches and can't get to crazy with the accuracy and point density.
